Mike, Mr. Seery makes a good point. A bad power valve would not dump gas into your crankcase. A fuel pump with a bad diafragam will allow gas to enter your crankcase.

Play it safe and rebuild the fuel pump along with your carburetor. Easy to do. Make an index mark on the top of the pump before you take it apart. BE CAREFUL NOT TO DROP ANYTHING INTO THE INTAKE WHEN YOU REMOVE AND REINSTALL THE FUEL PUMP & ROD.
